A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

## NHTSA's summary

While attempting to unbolt the third\-row seat to perform, or to gain access to perform another required repair, one or more of the bolts may not easily loosen. Applying addition force to loosen the bolts may cause the seat anchor body\-nuts to break free from their welds. The bolts will then just spin, not allowing the seat to be removed.
